IMPROVEMENT INDIANAPOLIS, INDIANA.

IN TILE-MILLS.

Specification forming part of Letters Patent No. 177.829, dated May 23, 1876 application filed .March 10, 1876.

To all whom 'it may concern:

Be it known that I, ARTEMUs N. RADLEY, of Indiana-polis, Marion county, Indiana, have l invented a new and useful Tile-Mill, of which line l l; Fig. 2, a section at the line 2 2; and

Fig. 3, a section at the line 3 3. Figs. 4 and 5 represent my roller by horizontal and vertical sections respectively. l: Fig. 6 illustrates another mode ot constructing the roller. l

A may represent any suitable tempering tub or hopper,-resting upon and secured to a customary double-endedbox, tube, or case,vB. C is ashai't, to which the temperingblades D and sweep-E, ofany approved form, are

fastened. Theshaft O extends dow-n through the box B, in' whose iioor its lower extremity is journaled. The portion of theshaft C that is included within the box B has the form of a double crank, F, whose wrist Gjs inclosed in a sheave or roller, G, composed ot' two semi-cylinders or semi-cylindrical segments, g g', to adapt them for application, and which are secured to each other and to'said wrist by means of bolts g g, which may either be. `screwed in, as in Fig. 4, or keyed in, as in Fig.

6. In the latter form the periphery of the roller is left wholly intact. The shaft G extends entirely through the double-headed piston H, of the form represented, the same being open from top to bottom, as at viand 7L', and at its sides, as at h and h, for the traverse ofthe shaft C and 0f the roller G. Bolted to the interior walls of my hollow piston are lining-plates I I', of chilled cast-iron or other suitable material, to save wear and reduce friction. J J are two customary throats for the passage of the tempered. clay into the box.

There is, of course, at each end of the box, a die or mouth-piece, to impart the desired form to tle but inasmuch as such molding devices are wellknown and are not concerned in my present invention, I have deemed it unnecessary to represent any in the present illustration.

I claim as new and of my invention- L'The combination of double'headed piston or plunger H, constructed with top and bottom slots It h', for the passa-ge of the shaft G, and side slots h h', for the passage ofthe roller Gr, with the shaft C, double-crank F, and wrist O as and for the purpose set forth.

2. The roller G, composed of segments g g', having fastenings g g', in combination with the double-headed piston or plunger H, and double crankshaft F C', as and for the purpose set forth..

3. The combination, with the double-headed piston or plunger H, crank F, and roller G, of the facing or lining plates I I.

In testimony of which invention I hereunto set my hand.-
